Abstract: An electric compressor includes an inverter, a housing with an opening, an inverter connector, a power connector, and a cable that electrically connects both connectors. The housing accommodates the inverter. The inverter connector includes a cover, an outer sealing member, and an inner sealing member. The cover includes an insertion hole through which the cable is inserted, and is disposed in the opening so as to position the cable in the opening. The outer sealing member is interposed between the opening and the cover. The inner sealing member is interposed between the insertion hole and the cable. The insertion hole includes a restriction portion that restricts a movement of the cable, and a fitting portion that is located closer to the inverter than the restriction portion and in which the inner sealing member is fitted. The insertion hole is narrower at the restriction portion than at the fitting portion.

Abstract: A cover assembly for on-board electric equipment includes a cover body and a connector including a terminal and a connector housing. The cover body includes a ferrous base metal body, and a Zn-based plating layer formed on a surface of the base metal body. The cover body has a through hole formed through the base metal body and the plating layer. The terminal is passed through the through hole and electrically connected to an electric circuit. The connector housing is formed on the cover body so as to surround the terminal. A laser mark is formed on the cover body. The laser mark has a circular shape about the through hole and penetrates the plating layer to the base metal body. The connector housing extends to the base metal body through the plating layer within the laser mark.

Abstract: A motor-driven compressor includes an electric motor driven by a motor driver, which includes a switching element that converts DC voltage from a battery to AC voltage. A control unit controls the switching operation of the switching element. A temperature detector detects the temperature of the switching element. The control unit suspends the switching operation of the switching element when the temperature detected by the temperature detector rises to a temperature threshold. The temperature threshold includes a first temperature threshold, corresponding to a withstand temperature of the switching element, and a second temperature threshold, which is higher than the first temperature threshold. The control unit switches the temperature threshold from the first temperature threshold to the second temperature threshold when the control unit activates a field weakening control that reduces counter electromotive force generated by the electric motor.

Abstract: To provide a motor-driven compressor which suppresses heat generation, enables power saving, exerts excellent durability, lowers a manufacturing cost, and hardly produces a defective product. The motor-driven compressor according to the present invention comprises a cover. The cover includes a first connector portion, first and second wires, and first and second resin portions. The first and second wires include first and second terminal portions having a cylindrical shape, lead portions, and first and second lid portions that are supported at opening end portions of the first and second terminal portions. The first and second lid portions close the opening end portions of the first and second terminal portions, and thereby prevent an insulating resin from entering the first and second terminal portions.

Abstract: A motor-driven compressor includes a compression portion, an electric motor, an inverter, and a metal housing. The inverter includes three-phase switching elements and a plastic holder that retains the three-phase switching elements. The housing includes a thermal radiation surface. The holder includes a metal spring. The holder is fixed to the housing using two fasteners. The three-phase switching elements are laid out between the two fasteners. The switching elements at opposite ends of the three-phase switching elements are pressed toward the thermal radiation surface by only the holder. The switching element at the middle of the three-phase switching elements is pressed toward the thermal radiation surface by the holder and the spring.

Abstract: Connectors are each integrated with a holder in a state in which bus bars are projected. A first projection and a second projection of the holder are respectively inserted in a first insertion hole and a second insertion hole in a circuit substrate. This determines positions of the holder and the circuit substrate relative to each other. The holder has coil lead wire insertion holes, capacitor lead wire insertion holes, and element lead wire insertion holes. These insertion holes extend in the same direction as the direction in which the bus bars project from the holder.

Abstract: A motor-driven compressor that includes a metal housing accommodating a compression unit and an electric motor, a cover coupled to the housing, wherein the cover includes a resin portion and a metal shield, and the shield blocks electromagnetic noise, and a bolt that couples the cover to the housing. The housing and the cover define an accommodating chamber that accommodates a motor driving circuit that drives the electric motor. The cover includes an insertion hole into which the bolt is insertable. The shield includes a seat that surrounds the insertion hole and is held between the bolt and the housing. The cover is configured to allow for an axial force of the bolt to be applied to the seat and not to the resin portion.
